I can't think of anybody off hand. At my school shop we have 2 machinists, one is kind of a hit and miss kind of guy, the other is awesome and always does good work. If you want i could get the number of the good machinist, but it will cost a little bit more money.
Go see the guys at Bilt Rite Cylinder Head Service. Phone: 243-5538. I have been building engines for years and these guys rock, in my opinion. Tell them Tom from Tech Works Engineering sent you. I have a very radical 280Z engine in my 240 that I had the guys at Bilt Rite do some machining on after I had welded up the combustion chambers and ports. They also have incredibly cheap Serdi valve seat machining services. Check them out.
Thanx guys, I'll check them out on monday. Things are finaly looking like there all going to come together for this thing. I'll be starting the porting on monday too. By the way, can I use grinding stones on the head, or will they just plug up? Am I going to have to find the 20-30$ carbide rasp style wheels? Anyways, gotta run.
